Answer:
C.21
Step-by-step explanation:
Answer:
((6x+3)(5x+3))/10
Step-by-step explanation:
Simplify:
=((6x+3)/4)((10x+6)/5)
=((6x+3)(10x+6))/20
=((6x+3)(5x+3))/10

Answer:
The binomial theorem allows you to write out the expansion of your polynomial immediately. (I feel like this is good enough)
Step-by-step explanation:
<em>It also allows you to answer such questions as:</em> "What is the coefficient of x20 in (1+x)100?" Its generalization to non-integer exponents allows you to get the expansion of (1−x)−1/2. There are all sorts of reasons.
The rink has a dimension of 200 ft* 85 ft = 17000 
depth = 1.5 inch that becomes
= 0.125 ft
So total volume of the water required = 17000* 0.125 = 2125 
Now 1 cubic foot of water= 7.480 gallons
Hence total gallons required are 2125 * 7.480 gallons = 15895 gallons.
Your slope is -6/1 and the y intercept is 2. i hope that helps!
